I'm in the process of having a bit of a clear out at the moment. I came across a big old file today, easy enough to put a new handle on it but it is also quite rusty, not crazy caked in the stuff but rusty all the same. Obviously I can't do a Wallace and grind the heck out of it and make it shiney, not if I want to use it as a file anyway, but is there any sensible way to bring it back to life?

I saw a couple of online references to using various acids to clean files, they even suggested that using them will re sharpen the file (not sure I understand how). But the idea of using acid that every says you have to wear a hazmat suit to touch does not appeal. I have also seen reference to using diluted (50%) distilled vinegar to remove rust, so was thinking about giving that a go.

Anyone got any experience of using diluted distilled vinegar to remove rust?

Terry I bought an old school issue set square from a reclaim yard recently and used the vinegar trick - worked brilliantly. Clearly wont resolve rust pitting but not too important on a file. Make sure all is submerged and then wait for 48 hrs, then wire brush and do it again until clean and rust free. Prob 2 dunkings required. I use the clear stuff from tesco. Use rubber gloves and do it in the open air.
